Description

  The subject of the present invention relates to a side wall protective cover for a non-slip chain and to a non-slip chain equipped with this type of side wall protective cover.

  The non-slip chain considered here has a tread surface net with, inter alia, a tortoise shell and at least one side wire with a chain member, and in the mounted state a wheel sidewall (especially a tire sidewall and / or Abuts the sidewalls of the tire outer surface). Here, the turtle metal fitting is connected to the side wire via binding means (for example, the shape of Harken) suspended from at least one chain member of the side wire, and each binding means has one side. A wall protective cover is provided.

  Sidewall protective covers of the type discussed here are used for anti-slip chains for vehicle tires and wheels and are used to protect the side walls and / or rims of vehicle tires to which the anti-slip chains are attached. In other words, there is a risk of damage to the side wall of the anti-slip chain, especially at the location where the tortoise shell metal fitting and the side wire are bound, and the action of the element used for binding (for example, metal harken) is usually Since it is larger than the members of the tire, contact with the surface of the tire sidewall may cause damage or even damage to the surface. The side wall protective cover wraps the binding element to some extent and prevents the wheel side wall from being damaged.

  Within the framework of the present disclosure, a “turtle shell” is each chain member or wire member that extends across the tread surface of the anti-slip chain tire and / or such chain member / wire member is side-faced. Used to connect to wires.

  Patent Document 1 discloses this type of apparatus. That is, it discloses a side wall protective device comprising a two-piece shell that can be opened, in which a chain member and a harken are contained, and in a state in which the chain is attached, the tread surface net portion is bound together. Only the portion of Harken that is used protrudes from the sidewall protection device. This device performs well, but is cumbersome in structure and tends to accumulate dirt inside.

  Patent Document 2 discloses a tension device for a snow chain in which a turtle metal fitting is suspended from a side wire via a harken. The tensioning device head member surrounds each chain member of the side wire, and the harken is suspended on the chain member, but the harken itself is free, so the harken may still contact the sidewall or rim. .

  Patent Document 3 describes a sidewall protection device that completely surrounds Harken together with a terminal member to which a chain of turtle shells belongs. Therefore, when the anti-slip chain is used, an additional load is generated on the turtle shell metal and the side wall protective cover itself, and the adjustment movement of the turtle shell metal causes the device to move with respect to the tire side.

  The object of the present invention is therefore to provide a side wall protection device which can be produced at low cost, can be simply mounted to cover the binding site and overcomes the above-mentioned drawbacks of known devices.

  This problem is solved by a sidewall protective cover that uses a U-shaped body to accommodate chain wire chain members present on the sidewalls of the vehicle wheels. Here, the U-shaped body has two wings connected along the back surface, the wings enclosing a space accommodating the chain member, and on the side facing inward of at least one of the wings, the chain member and And / or a holding element in the form of a protrusion for anchoring the binding element suspended on the chain member between the wings.

  As described above, this side wall protective cover is used for the non-slip chain of the type described at the beginning. In this anti-slip chain, each side means is provided with one side wall protective cover. The binding means surround at least one chain member of each of the side wires. Here, in order to facilitate the binding of the turtle shell metal fitting, a part of the binding means (for example, Harken) used for binding protrudes from the sidewall protective cover.

  This special shape solves the above problem surprisingly easily and appropriately. Since the side wall protective cover of the present invention is U-shaped, the constituent member can be easily inserted onto the chain member involved in the binding location and the binding element itself, like a clip or a capsule. On the basis of the U-shape, the two legs of this U are formed by two wings that butt through the back part on one side (corresponding to the curve below U), while the wings are also independent of each other. Which extend substantially parallel to each other or form opposing flaps like each other, like the two shells of a bivalve. This achieves cost-effective manufacturing and simple assembly by insertion.

  In a preferred realization of the side wall protective cover according to the invention, the U-shaped body, i.e. the two wings and the back part, are constructed in one piece in order to further simplify the structure.

  In order to be able to securely fix the side wall protective cover of the present invention, the holding element can be configured as a nose overhanging, which nose grips the chain member (for example for accommodating the chain member) Cooperating with the bottom of the space) or engaging the ring of the chain member, thus anchoring the chain member with the side wall protective cover relaxed. In addition, the insertion process can be facilitated by the fact that the two wings can be deflected to each other so that at least the chain member can be introduced, based on the flexibility of the back surface.

  In order to prevent the cover from sliding down from the binding point on the non-slip chain, the wing can have a strip on its inside that starts from the inside of the back part and extends away from it, Here, the holding element is arranged on the strip of the wing. In this case, each of the two wings has a strip of this kind inside, and the holding element is arranged on the strip of each wing provided in contact with the sidewall.

  Furthermore, it is advantageous if each wing provided for abutting against the wheel sides has a substantially flat outer abutment surface. Furthermore, the wing opposite to the wing can have a shell-like curve, which can hold the binding means suspended on the chain member moored between the wings in that position. It is configured. Here, the shell-like curve is curved outward (or forward), so that a hollow recess is formed inside the second wing.

  The invention, including further advantages, will now be described in detail on the basis of non-limiting examples shown in the drawings.

It is the outer surface schematic of a tire which has a non-slip chain provided with the sidewall protective cover of the present invention. FIG. 2 is a partially enlarged view of FIG. 1 in a position where one of the sidewall protection covers is attached. FIG. 2 is a partial view of the outer side wire of the non-slip chain of FIG. 1 without a side wall protective cover, and is a perspective view of Harken for tying the side wire to a turtle shell, suspended from a chain member of the side wire It is shown in the figure.

FIG. 10 is a cross-sectional view taken along the center plane of the side wall protective cover in a state of being attached to the side wires, corresponding to FIG.

  As shown in FIGS. 1 and 2, the anti-slip chain 1 according to the present invention has a tread surface net provided with a turtle metal fitting 2, and a side wire 6 that comes into contact with the tire sidewall 3 while being mounted on a wheel. Here, the side wire is the wire edge of the non-slip chain 1 extending along the tire sidewall 3 and is preferably configured to close itself in a ring shape, at least partially, Often the whole can be realized as a chain. In the illustrated embodiment, the side wire 6 is not used as a pull wire, but in another embodiment the side wire can be configured as a pull wire, for example by including a spring element or pull element.

  As can be seen from FIG. 3, the turtle shell 2 is connected to the side wires 6 through binding means suspended from at least one chain member 4 of each side wire 6. This binding means is here realized as Harken 5. The location where the binding means / Haken 5 is fixed to the side wire 6 will be referred to as a binding location below. A side wall protective cover 11 including a Harken 5 and at least one chain member 4 is provided at each binding location. The side wall protective cover 11 is configured as a clip that can be inserted on the chain member 4 and the harken 5 in the illustrated shape. Without this clip, the metal harken 5 may come into contact with the surface of the wheel sidewall, where there is surface damage, such as scratching the wheel rim, or improper installation, for example Failure can be caused by rubbing on the wheel sidewalls. The clip 11 used as a side wall protective cover has a relatively smooth surface with respect to the wheel side wall, thereby avoiding damage to the wheel rim.

  In addition, to facilitate attachment and removal, at least one of the clips 11 can be made particularly noticeable, for example by special coloring. Thus, in FIG. 1, the clip 12 is shown particularly prominently (shown in dotted lines). By marking the clip 12, the exact location of the chain on the wheel can be indicated. The mark can be made by, for example, the clip 12 having a color different from that of the other clip 11.

  FIG. 4 shows the binding location shown in FIG. 3 with the clip 11 inserted. The chain member 4 is completely inside the cover 11, while a portion of the Harken 5 used for binding the turtle shell 2 protrudes from the cover 11.

  5 to 9 show the clip 11 from various viewing directions, FIG. 5 is a perspective view, FIG. 6 is a front view, FIG. 7 is a plan view, FIG. 8 is a side view (from the left), and FIG. FIG. 8 is a sectional view taken along the center plane m (FIGS. 6 and 7) of the clip. The expressions “up / down”, “front / back”, “right / left”, and the like are based on the state in which the back surface of the clip 11 is in contact with the (horizontal) base. Extends upwards, each with one wing pointing forward and backward, but for example the spatial orientation or the current orientation of the clip on the chain (possibly attached to a rotating wheel) It is not a standard. In this representation, the rear side is formed by each wing 13 abutting against the wheel sidewall with the clip attached, while the front wing 14 extends at a distance from the sidewall, Thus, when looking at the side of the wheel, the front side of the clip 11 is observed.

  The body of the clip 11 is substantially formed by two wings or sides 13,14. These are joined only along their downwardly extending edges in FIG. 6 and are not otherwise in contact with each other. As a result, a substantially U-shaped basic shape is obtained. The back surface 12 forming the connection between the two wings 13, 14 is preferably located on the side of the clip oriented in the assembled state towards the hub edge, as in this embodiment. . (Shown in FIGS. 2 and 10)

  The clip has a plane of symmetry m, which extends through the center of the back surface 12 and the wings 13,14. Further, the two wings 13 and 14 may be mirror objects of each other, but in the illustrated embodiment, they are implemented slightly differently as will be described further below.

  The wings 13 and 14 have a space, and this space further accommodates a harken 5 (or more generally a tortoise shell metal fitting 2) suspended from the side wire 6 so as to receive the chain member 4 of the side wire. It is designed to accommodate at least a part of the element for binding. This part is a part that comes into contact with the sidewall 3 of the wheel if the sidewall protective cover is not attached. A strip (or web) 15, 16 extends inside the wings 13, 14, i.e. along the center line. One of the strips, preferably the rear strip 15 present inside the rear wing 13, has a nose 17. The nose 17 in the illustrated embodiment is one-piece with the strip 15 or wing 13 in connection with the characteristic as a protrusion.

  FIGS. 10 to 13 show the clip 11 together with a part of the side wire 6 (see FIG. 4) in a state where it is correctly inserted into the binding part (= the chain member 4 having the Harken 5). Here, the chain members 4 ′, 4 ″ of the side wire 6 connected to the chain member 4 protrude. With respect to the viewing direction shown in the drawing, FIGS. 10 to 13 correspond to FIGS. 6 to 9, respectively. Is clearly held by the chain member 4 and the harken 5. In particular, as can be seen from FIGS. 12 and 13, the strips 15 and 16 hold the chain member 4 in the vertical position in the clip 11, The strips 15 and 16 are engaged between the two legs of the harken 5 to prevent the halken 5 from sliding down sideways. The nose 17 is used as a protruding holding means in the present invention.

  Referring to FIGS. 8 and 12, the rear wing 13 has a flat, preferably flat outer surface, which has no protrusions or ridges, and without damage to the wheel sidewalls, together with the clip 11. It can contact the wheel sidewall. In contrast, the forward wing 14 is preferably slightly curved outward (i.e. forward) to better anchor the elements of the side wire 6 held inside the clip.

  The body of the clip 11 is preferably constructed in one piece and is made of a shape-stable artificial resin, such as polyamide, which allows some degree of flexible deformability at least on the back surface 12. Other artificial resins that are not brittle, such as polypropylene and polyester, can also be used.

  When the clip 11 is attached to the binding site, the clip 11 is moved to the harken 5 so that the rear web enters between the two legs of the harken 5. The elasticity of the material of the clip body opens the clip 11 so that the chain member 4 can be guided through the nose 17 and the nose 17 is firmly closed in the final position. Here, the oblique upper edge of the web 15 facilitates the introduction of the chain member 4. In order to release the clip, the clip can be lifted again elastically, whereby the nose 17 releases the chain member 4. But removing the clip is usually not necessary.

  As is obvious to a person skilled in the art, the invention is not limited to the embodiments shown, but rather the invention is all embodiments which can be understood and implemented by a person skilled in the art within the scope of the protection scope of the claims. It is intended for.
